1 单击首选项 展开菜单，单击首选项，然后找到Raspberry Pi Configuration。2 单击Interfaces 在新窗口栏目中单击Interfaces。3 开启SPI 在下面找到SPI并开启SPI就好。
Enable SPI Configure your Pi and enable the SPI sudo raspi-config Select Advanced Options -> SPI -> <YES> to enable the SPI driver by kernel. Then you can check if the SPI is enabled: lsmod If SPI enabled, the terminal echoes an spi-bcm2835 device. You can check the GPIO with the...
SPI通信是一种串行外设接口通信协议,用于在Raspberry Pi和Arduino之间进行数据传输。SPI代表串行外设接口(Serial Peripheral Interface),它允许多个设备通...
Raspi-config 选择:P4 SPI,进入SPI接口的设置 Interfaceing Options 选择:<是>,开启SPI Enable SPI 选择:<确定>,确认SPI的开启 Confirm SPI enabled 确认完成后会回到主页面,选择:<Finish>,完成配置 Raspi-config 此后可能涉及到需要重启,按照提示重启,或者在终端输入: pi@Cocoonshu sudo reboot 2. 连接TFT液晶...
In this tutorial, you will learn how to enable the SPI interface on the Raspberry Pi. SPI stands for serial peripheral interface and is a synchronous serial communication interface that is used for one device to send data to another. LATEST VIDEOS This video cannot be played because of a ...
使用PI测试FPGA spidev0.1 即 SPI0 MISO、SPI0 MOSI、SPI0 CLK 和 CE1 连接到 FPGA。 下面展示的是如何使用终端发送SPI字节序列来读写字节流。这是一个例子: # printf '\xA2\x1\x2\x3\x0\x0\x4\x11\x22\x33\x44\0' | spi-pipe -m 0 -s 1000000 -d /dev/spidev0.1 | hexdump -C 0000000...
pi@raspberrypi:~$ i2cdetect -y 1 Error: Could not open file dev/i2c-1' or `/dev/i2c/1': No such file or directory 无设备目录 解决方法: 方法一:raspi-config,进入Interfacing Options高级设置,将spi与i2c设置为enable,reboot; 方法二:blacklist里面有i2c,所以i2cdetect检测不到dev里面的设备,现在...
I2C on Pi Configuration The I2C peripheral is not turned on by default. There are two methods to adjust the settings just like the SPI. To enable it, do the following. Raspberry Pi Configurationvia Desktop GUI You can use the Desktop GUI by heading to thePi Start Menu>Preferences>Raspberry...
